Benefits of technology
The patent describes a method where a non-PDN node sends its current table for its allocated slots in both static and potential dynamic allocations to speed up the convergence times.
Problems solved by technology
Some nodes in a mobile network, known as potentially disruptive nodes, may have a negative impact on performances because of their wide connectivity compared to the one of the network average.
One of the problems with such nodes is that they can reduce the amount of slot spatial reuse in a mobile network.
Moreover, PDN nodes can become routing bottlenecks if they have to relay too much data.

Embodiment Construction
[0057]FIG. 1 is a schematic representation of a mobile ad-hoc network comprising several radio communication nodes Ni. Some of them are potentially disruptive nodes (PDN) such as defined above.
[0058]The radio communication nodes are, for example, mobile phones 104, 105, 106, portable computers 101, 102, 103, electronic tablets 107, 108, 109, or aerial vehicle 100. More generally, a node is an equipment that comprises means of transmitting / receiving data on a selected radio channel to / from other nodes of the network, or other networks. The neighbouring nodes that can be reached directly without the use of another node are called one-hop or 1-hop neighbour nodes.
[0059]The method proposed according to the present invention is based on the use of static and dynamic S-SLOT allocation mechanisms. Proposed solution according to the invention uses a new concept of normal sub-cycle (normal S-cycle) and improved sub-cycle (improved S-cycle) allowing the PDN nodes to be managed. A node needs t...

A method is provided for managing the spatial reuse of slots in a mobile network comprising several nodes Ni, said network comprising one or more Potentially Disruptive Nodes (PDN), said nodes Ni and PDN comprising a local table, a global table, and a summary of the global table comprising the interleaving of two sub-cycles: a first sub-cycle, the normal S-cycle, where S-SLOTs are all assigned statically and where each node has one or only one S-SLOT allocation, a second sub-cycle, the improved S-cycle, where each node has one S-SLOT assigned statically, and where for all nodes except PDN nodes, one or more additional S-SLOTs is assigned dynamically when topology makes it possible, dynamic S-SLOT allocation being equitably shared in a 2-hop neighborhood, and determined by performing S-SLOT spatial reuse.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 14 / 234,371, which is a National Stage of International patent application PCT / EP2012 / 064071, filed on Jul. 18, 2012, which claims priority to foreign European patent application No. EP 11290335.6, filed on Jul. 22, 2011, the disclosures of which are incorporated by reference in their entirety.FIELD OF THE INVENTION[0002]The invention relates to a method for managing spatial reuse on a single channel in a mobile ad-hoc network comprising one or more potentially disruptive nodes.[0003]A potentially disruptive node or PDN is defined as a node having a wide connectivity as explained below.BACKGROUND[0004]A mobile network, for example a MANET (Mobile Ad-hoc Network), is a kind of network that has the capability to reconfigure itself and change locations. Such network is composed of a plurality of moving communication nodes able to emit (transmit) and to receive data from ea...
